🧾 My energy bill is wrong or far too high in Slovenia. What now?

The short answer

Most bill problems come from estimated meter readings, a wrong meter number or a changed advance payment. You have the right to a correct bill based on your real use.

📜 The rules in Slovenia

What to do first

First complain to your supplier (free internal procedure). If it rejects you or does not answer within one month, go to the independent ADR body named by that supplier; the supplier pays the costs. Disputes with the grid operator go to the Agencija za energijo.

Protection against cut-off

The grid operator must warn a household at least 10 days before a planned disconnection, after an earlier notice. Before cutting, it must tell you about emergency supply for vulnerable customers and what proof to send. Your supplier must explain alternatives by the last reminder at the latest.

❓ Questions

Should I pay a bill I dispute?

If you can, pay the part you agree with and dispute the rest in writing. That protects you best.

Can the supplier estimate my use?

Yes, if no reading was available. You can always send a real reading and ask for a correction.

How far back can they bill me?

The limits differ per country. Ask the energy regulator if you get a large back-bill.
